When talking to the guy at Ron Davis Radiators, I asked about using a 180 thermostat and he explained to me why not to use it and how the cooling system works.

I'm interested as to the "why nots" they mentioned. Hundreds, if not thousands, of Magnum engines are running 180's right now and have been for years with no issues and its pretty much a requirement once you start adding more ignition advance and trimmer fuel maps

I had heard about some antifreeze being very bad for aluminum radiators, when asking about this he said to use the Prestone premixed which features a blend of 50% antifreeze/coolant for temperature and corrosion protection and 50% demineralized water.

Something was said about running a ground to the radiator, but I will need to find out more about that.

With help from them and the people on this forum I hope to set up the perfect cooling system.

Should be delivered today according to UPS. It shipped promptly. If its junk, I'm stuck with it. I knew that up front tho. Pics and opinion on the way. I can pressure test it in my garage, so I'll do that first with plain water.

Just did a major AC delete. Removed compressor, condensor and accumulator, lines and hoses. I may do an engine oil cooler and filter relocation kit. The filter would fit perfectly in the accumulator's old spot. Also adding this PS coolerhttp://www.amazon.com/dp/B004XONO8E/...0_M2T1_SC_dp_1

Oh and removed the efan. Going back to clutch. I'm done with electric fans.

Almost all radiators are from China except for the Griffin and Davis. I say almost because a few may still be hecho en mexico. Which one are you running?

I only use the 94 ZJ on weekends for our 'saturday drive'. So during the summer we leave early in the morning when it is cool and we go to mountains at 8000+ ft. elevation for the day. Then we come back at night when it is cool. And we use these

I am running the cheapest radiator rock auto had for about 100 bucks or so. I told them to make sure it was made in a third world country under terrible conditions. I can almost smell the fear of the worker who made it when it warms up!
